            Create a single query suitable for use by all subsearchers (in 1-1
            correspondence with queries). This is an optimization of the OR of
            all queries. We handle the common optimization cases of equal
            queries and overlapping clauses of boolean OR queries (as generated
            by MultiTermQuery.rewrite()).
            Be careful overriding this method as queries[0] determines which
            method will be called and is not necessarily of the same type as
            the other queries.

            <summary> This method can be overridden by extending classes to return a sentinel

            that the code which uses that queue can always assume it's full and only
            change the top without attempting to insert any new object.<br/>
            
            Those sentinel values should always compare worse than any non-sentinel
            value (i.e., {@link #LessThan(Object, Object)} should always favor the
            non-sentinel values).<br/>
            
            By default, this method returns false, which means the queue will not be

            If this method is extended to return a non-null value, then the following
            usage pattern is recommended:
            
            <pre>
            // extends getSentinelObject() to return a non-null value.
            PriorityQueue pq = new MyQueue(numHits);

            MyObject pqTop = (MyObject) pq.top();

            // now in order to add a new element, which is 'better' than top (after 
            // you've verified it is better), it is as simple as:
            pqTop.change().
            pqTop = pq.updateTop();
            </pre>
            
            <b>NOTE:</b> if this method returns a non-null value, it will be called by
            {@link #Initialize(int)} {@link #Size()} times, relying on a new object to
            be returned and will not check if it's null again. Therefore you should
            ensure any call to this method creates a new instance and behaves
            consistently, e.g., it cannot return null if it previously returned
            non-null.

            faster, but indexing speed is slower.  With larger
            values, more RAM is used during indexing, and while
            searches on unoptimized indices are slower, indexing is
            faster.  Thus larger values (&gt; 10) are best for batch
            index creation, and smaller values (&lt; 10) for indices
            that are interactively maintained.

        <member name="T:Lucene.Net.Documents.NumericField">
            <summary> <p/>This class provides a {@link Field} that enables indexing
            of numeric values for efficient range filtering and
            sorting.  Here's an example usage, adding an int value:
            <pre>
            document.add(new NumericField(name).setIntValue(value));
            </pre>
            
            For optimal performance, re-use the
            <code>NumericField</code> and {@link Document} instance for more than
            one document:
            
            <pre>
            NumericField field = new NumericField(name);
            Document document = new Document();
            document.add(field);
            
            for(all documents) {
            ...
            field.setIntValue(value)
            writer.addDocument(document);
            ...
            }
            </pre>
            
            <p/>The java native types <code>int</code>, <code>long</code>,
            <code>float</code> and <code>double</code> are
            directly supported.  However, any value that can be
            converted into these native types can also be indexed.
            For example, date/time values represented by a
            {@link java.util.Date} can be translated into a long
            value using the {@link java.util.Date#getTime} method.  If you
            don't need millisecond precision, you can quantize the
            value, either by dividing the result of
            {@link java.util.Date#getTime} or using the separate getters
            (for year, month, etc.) to construct an <code>int</code> or
            <code>long</code> value.<p/>
            
            <p/>To perform range querying or filtering against a
            <code>NumericField</code>, use {@link NumericRangeQuery} or {@link
            NumericRangeFilter}.  To sort according to a
            <code>NumericField</code>, use the normal numeric sort types, eg
            {@link SortField#INT} (note that {@link SortField#AUTO}
            will not work with these fields).  <code>NumericField</code> values
            can also be loaded directly from {@link FieldCache}.<p/>
            
            <p/>By default, a <code>NumericField</code>'s value is not stored but
            is indexed for range filtering and sorting.  You can use
            the {@link #NumericField(String,Field.Store,boolean)}
            constructor if you need to change these defaults.<p/>
            
            <p/>You may add the same field name as a <code>NumericField</code> to
            the same document more than once.  Range querying and
            filtering will be the logical OR of all values; so a range query
            will hit all documents that have at least one value in
            the range. However sort behavior is not defined.  If you need to sort,
            you should separately index a single-valued <code>NumericField</code>.<p/>
            
            <p/>A <code>NumericField</code> will consume somewhat more disk space
            in the index than an ordinary single-valued field.
            However, for a typical index that includes substantial
            textual content per document, this increase will likely
            be in the noise. <p/>
            
            <p/>Within Lucene, each numeric value is indexed as a
            <em>trie</em> structure, where each term is logically
            assigned to larger and larger pre-defined brackets (which
            are simply lower-precision representations of the value).
            The step size between each successive bracket is called the
            <code>precisionStep</code>, measured in bits.  Smaller
            <code>precisionStep</code> values result in larger number
            of brackets, which consumes more disk space in the index
            but may result in faster range search performance.  The
            default value, 4, was selected for a reasonable tradeoff
            of disk space consumption versus performance.  You can
            use the expert constructor {@link
            #NumericField(String,int,Field.Store,boolean)} if you'd
            like to change the value.  Note that you must also
            specify a congruent value when creating {@link
            NumericRangeQuery} or {@link NumericRangeFilter}.
            For low cardinality fields larger precision steps are good.
            If the cardinality is &lt; 100, it is fair
            to use {@link Integer#MAX_VALUE}, which produces one
            term per value.
            
            <p/>For more information on the internals of numeric trie
            indexing, including the <a
            href="../search/NumericRangeQuery.html#precisionStepDesc"><code>precisionStep</code></a>
            configuration, see {@link NumericRangeQuery}. The format of
            indexed values is described in {@link NumericUtils}.
            
            <p/>If you only need to sort by numeric value, and never
            run range querying/filtering, you can index using a
            <code>precisionStep</code> of {@link Integer#MAX_VALUE}.
            This will minimize disk space consumed. <p/>
            
            <p/>More advanced users can instead use {@link
            NumericTokenStream} directly, when indexing numbers. This
            class is a wrapper around this token stream type for
            easier, more intuitive usage.<p/>
            
            <p/><b>NOTE:</b> This class is only used during
            indexing. When retrieving the stored field value from a
            {@link Document} instance after search, you will get a
            conventional {@link Fieldable} instance where the numeric
            values are returned as {@link String}s (according to
            <code>toString(value)</code> of the used data type).

            <summary> A <code>TokenStream</code> enumerates the sequence of tokens, either from
            {@link Field}s of a {@link Document} or from query text.
            <p/>
            This is an abstract class. Concrete subclasses are:
            <ul>
            <li>{@link Tokenizer}, a <code>TokenStream</code> whose input is a Reader; and</li>
            <li>{@link TokenFilter}, a <code>TokenStream</code> whose input is another
            <code>TokenStream</code>.</li>
            </ul>
            A new <code>TokenStream</code> API has been introduced with Lucene 2.9. This API
            has moved from being {@link Token} based to {@link Attribute} based. While
            {@link Token} still exists in 2.9 as a convenience class, the preferred way
            to store the information of a {@link Token} is to use {@link AttributeImpl}s.
            <p/>
            <code>TokenStream</code> now extends {@link AttributeSource}, which provides
            access to all of the token {@link Attribute}s for the <code>TokenStream</code>.
            Note that only one instance per {@link AttributeImpl} is created and reused
            for every token. This approach reduces object creation and allows local
            caching of references to the {@link AttributeImpl}s. See
            {@link #IncrementToken()} for further details.
            <p/>
            <b>The workflow of the new <code>TokenStream</code> API is as follows:</b>
            <ol>
            <li>Instantiation of <code>TokenStream</code>/{@link TokenFilter}s which add/get
            attributes to/from the {@link AttributeSource}.</li>
            <li>The consumer calls {@link TokenStream#Reset()}.</li>
            <li>The consumer retrieves attributes from the stream and stores local
            references to all attributes it wants to access</li>
            <li>The consumer calls {@link #IncrementToken()} until it returns false and
            consumes the attributes after each call.</li>
            <li>The consumer calls {@link #End()} so that any end-of-stream operations
            can be performed.</li>
            <li>The consumer calls {@link #Close()} to release any resource when finished
            using the <code>TokenStream</code></li>
            </ol>
            To make sure that filters and consumers know which attributes are available,
            the attributes must be added during instantiation. Filters and consumers are
            not required to check for availability of attributes in
            {@link #IncrementToken()}.
            <p/>
            You can find some example code for the new API in the analysis package level
            Javadoc.
            <p/>
            Sometimes it is desirable to capture a current state of a <code>TokenStream</code>
            , e. g. for buffering purposes (see {@link CachingTokenFilter},
            {@link TeeSinkTokenFilter}). For this usecase
            {@link AttributeSource#CaptureState} and {@link AttributeSource#RestoreState}

            <summary> Consumers (i.e., {@link IndexWriter}) use this method to advance the stream to
            the next token. Implementing classes must implement this method and update
            the appropriate {@link AttributeImpl}s with the attributes of the next
            token.
            
            The producer must make no assumptions about the attributes after the
            method has been returned: the caller may arbitrarily change it. If the
            producer needs to preserve the state for subsequent calls, it can use
            {@link #captureState} to create a copy of the current attribute state.
            
            This method is called for every token of a document, so an efficient
            implementation is crucial for good performance. To avoid calls to
            {@link #AddAttribute(Class)} and {@link #GetAttribute(Class)} or downcasts,
            references to all {@link AttributeImpl}s that this stream uses should be
            retrieved during instantiation.
            
            To ensure that filters and consumers know which attributes are available,
            the attributes must be added during instantiation. Filters and consumers
            are not required to check for availability of attributes in

            should upgrade to use this feature.

            This method can be used to perform any end-of-stream operations, such as
            setting the final offset of a stream. The final offset of a stream might
            differ from the offset of the last token eg in case one or more whitespaces
            followed after the last token, but a {@link WhitespaceTokenizer} was used.

            returned. Callers may re-use a single Token instance for successive calls
            to this method.
            
            This implicitly defines a "contract" between consumers (callers of this
            method) and producers (implementations of this method that are the source
            for tokens):

            <summary>An "open" BitSet implementation that allows direct access to the array of words
            storing the bits.
            <p/>
            Unlike java.util.bitset, the fact that bits are packed into an array of longs
            is part of the interface.  This allows efficient implementation of other algorithms
            by someone other than the author.  It also allows one to efficiently implement
            alternate serialization or interchange formats.
            <p/>
            <code>OpenBitSet</code> is faster than <code>java.util.BitSet</code> in most operations
            and *much* faster at calculating cardinality of sets and results of set operations.
            It can also handle sets of larger cardinality (up to 64 * 2**32-1)
            <p/>
            The goals of <code>OpenBitSet</code> are the fastest implementation possible, and
            maximum code reuse.  Extra safety and encapsulation
            may always be built on top, but if that's built in, the cost can never be removed (and
            hence people re-implement their own version in order to get better performance).
            If you want a "safe", totally encapsulated (and slower and limited) BitSet
            class, use <code>java.util.BitSet</code>.

            <p/>The fields used to determine sort order must be carefully chosen.
            Documents must contain a single term in such a field,
            and the value of the term should indicate the document's relative position in
            a given sort order.  The field must be indexed, but should not be tokenized,
            and does not need to be stored (unless you happen to want it back with the
            rest of your document data).  In other words:
            
            <p/><code>document.add (new Field ("byNumber", Integer.toString(x), Field.Store.NO, Field.Index.NOT_ANALYZED));</code><p/>
            
            
            <p/><h3>Valid Types of Values</h3>
            
            <p/>There are four possible kinds of term values which may be put into
            sorting fields: Integers, Longs, Floats, or Strings.  Unless
            {@link SortField SortField} objects are specified, the type of value
            in the field is determined by parsing the first term in the field.
            
            <p/>Integer term values should contain only digits and an optional
            preceding negative sign.  Values must be base 10 and in the range
            <code>Integer.MIN_VALUE</code> and <code>Integer.MAX_VALUE</code> inclusive.
            Documents which should appear first in the sort
            should have low value integers, later documents high values
            (i.e. the documents should be numbered <code>1..n</code> where
            <code>1</code> is the first and <code>n</code> the last).
            
            <p/>Long term values should contain only digits and an optional
            preceding negative sign.  Values must be base 10 and in the range
            <code>Long.MIN_VALUE</code> and <code>Long.MAX_VALUE</code> inclusive.
            Documents which should appear first in the sort
            should have low value integers, later documents high values.
            
            <p/>Float term values should conform to values accepted by
            {@link Float Float.valueOf(String)} (except that <code>NaN</code>
            and <code>Infinity</code> are not supported).
            Documents which should appear first in the sort
            should have low values, later documents high values.
            
            <p/>String term values can contain any valid String, but should
            not be tokenized.  The values are sorted according to their
            {@link Comparable natural order}.  Note that using this type
            of term value has higher memory requirements than the other
            two types.
            
            <p/><h3>Object Reuse</h3>
            
            <p/>One of these objects can be
            used multiple times and the sort order changed between usages.
            
            <p/>This class is thread safe.
            
            <p/><h3>Memory Usage</h3>
            
            <p/>Sorting uses of caches of term values maintained by the
            internal HitQueue(s).  The cache is static and contains an integer
            or float array of length <code>IndexReader.maxDoc()</code> for each field
            name for which a sort is performed.  In other words, the size of the
            cache in bytes is:
            
            <p/><code>4 * IndexReader.maxDoc() * (# of different fields actually used to sort)</code>
            
            <p/>For String fields, the cache is larger: in addition to the
            above array, the value of every term in the field is kept in memory.
            If there are many unique terms in the field, this could
            be quite large.
            
            <p/>Note that the size of the cache is not affected by how many
            fields are in the index and <i>might</i> be used to sort - only by
            the ones actually used to sort a result set.

            gather raw results from a search, and implement sorting
            or custom result filtering, collation, etc. <p/>
            
            <p/>As of 2.9, this class replaces the deprecated
            HitCollector, and offers an API for efficient collection
            of hits across sequential {@link IndexReader}s. {@link
            IndexSearcher} advances the collector through each of the
            sub readers, in an arbitrary order. This results in a
            higher performance means of collection.<p/>
            
            <p/>Lucene's core collectors are derived from Collector.
            Likely your application can use one of these classes, or
            subclass {@link TopDocsCollector}, instead of
            implementing Collector directly:
            
            <ul>
            
            <li>{@link TopDocsCollector} is an abstract base class
            that assumes you will retrieve the top N docs,
            according to some criteria, after collection is
            done.  </li>
            
            <li>{@link TopScoreDocCollector} is a concrete subclass
            {@link TopDocsCollector} and sorts according to score +
            docID.  This is used internally by the {@link
            IndexSearcher} search methods that do not take an
            explicit {@link Sort}. It is likely the most frequently
            used collector.</li>
            
            <li>{@link TopFieldCollector} subclasses {@link
            TopDocsCollector} and sorts according to a specified
            {@link Sort} object (sort by field).  This is used
            internally by the {@link IndexSearcher} search methods
            that take an explicit {@link Sort}.</li>
            
            <li>{@link TimeLimitingCollector}, which wraps any other
            Collector and aborts the search if it's taken too much
            time, will subclass Collector in 3.0 (presently it
            subclasses the deprecated HitCollector).</li>
            
            <li>{@link PositiveScoresOnlyCollector} wraps any other
            Collector and prevents collection of hits whose score
            is &lt;= 0.0</li>
            
            </ul>
            
            <p/>Collector decouples the score from the collected doc:
            the score computation is skipped entirely if it's not
            needed.  Collectors that do need the score should
            implement the {@link #setScorer} method, to hold onto the
            passed {@link Scorer} instance, and call {@link
            Scorer#Score()} within the collect method to compute the
            current hit's score.  If your collector may request the
            score for a single hit multiple times, you should use
            {@link ScoreCachingWrappingScorer}. <p/>
            
            <p/><b>NOTE:</b> The doc that is passed to the collect
            method is relative to the current reader. If your
            collector needs to resolve this to the docID space of the
            Multi*Reader, you must re-base it by recording the
            docBase from the most recent setNextReader call.  Here's
            a simple example showing how to collect docIDs into a
            BitSet:<p/>
            
            <pre>
            Searcher searcher = new IndexSearcher(indexReader);
            final BitSet bits = new BitSet(indexReader.maxDoc());
            searcher.search(query, new Collector() {
            private int docBase;
            
            <em>// ignore scorer</em>
            public void setScorer(Scorer scorer) {
            }
            
            <em>// accept docs out of order (for a BitSet it doesn't matter)</em>
            public boolean acceptsDocsOutOfOrder() {
            return true;
            }
            
            public void collect(int doc) {
            bits.set(doc + docBase);
            }
            
            public void setNextReader(IndexReader reader, int docBase) {
            this.docBase = docBase;
            }
            });
            </pre>
            
            <p/>Not all collectors will need to rebase the docID.  For
            example, a collector that simply counts the total number
            of hits would skip it.<p/>
            
            <p/><b>NOTE:</b> Prior to 2.9, Lucene silently filtered
            out hits with score &lt;= 0.  As of 2.9, the core Collectors
            no longer do that.  It's very unusual to have such hits
            (a negative query boost, or function query returning
            negative custom scores, could cause it to happen).  If
            you need that behavior, use {@link
            PositiveScoresOnlyCollector}.<p/>
            
            <p/><b>NOTE:</b> This API is experimental and might change
            in incompatible ways in the next release.<p/>

            NOTE: some collectors can work in either mode, with a more efficient
            implementation for in-order docs collection. If your collector can work in
            either mode, it is recommended that you create two variants of it, since
            some queries work much faster if out-of-order collection is supported by a
            {@link Collector}.

            <summary> Provides methods for sanity checking that entries in the FieldCache 
            are not wasteful or inconsistent.
            <p/>
            <p/>
            Lucene 2.9 Introduced numerous enhancements into how the FieldCache 
            is used by the low levels of Lucene searching (for Sorting and 
            ValueSourceQueries) to improve both the speed for Sorting, as well 
            as reopening of IndexReaders.  But these changes have shifted the 
            usage of FieldCache from "top level" IndexReaders (frequently a 
            MultiReader or DirectoryReader) down to the leaf level SegmentReaders.  
            As a result, existing applications that directly access the FieldCache 
            may find RAM usage increase significantly when upgrading to 2.9 or 
            Later.  This class provides an API for these applications (or their 
            Unit tests) to check at run time if the FieldCache contains "insane" 
            usages of the FieldCache.
            <p/>
            <p/>
            <b>EXPERIMENTAL API:</b> This API is considered extremely advanced and 
            experimental.  It may be removed or altered w/o warning in future releases 
            of Lucene.

            <summary>An <code>IndexWriter</code> creates and maintains an index.
            <p/>The <code>create</code> argument to the {@link
            #IndexWriter(Directory, Analyzer, boolean) constructor} determines 
            whether a new index is created, or whether an existing index is
            opened.  Note that you can open an index with <code>create=true</code>
            even while readers are using the index.  The old readers will 
            continue to search the "point in time" snapshot they had opened, 
            and won't see the newly created index until they re-open.  There are
            also {@link #IndexWriter(Directory, Analyzer) constructors}
            with no <code>create</code> argument which will create a new index
            if there is not already an index at the provided path and otherwise 
            open the existing index.<p/>
            <p/>In either case, documents are added with {@link #AddDocument(Document)
            addDocument} and removed with {@link #DeleteDocuments(Term)} or {@link
            #DeleteDocuments(Query)}. A document can be updated with {@link
            #UpdateDocument(Term, Document) updateDocument} (which just deletes
            and then adds the entire document). When finished adding, deleting 
            and updating documents, {@link #Close() close} should be called.<p/>
            <a name="flush"></a>
            <p/>These changes are buffered in memory and periodically
            flushed to the {@link Directory} (during the above method
            calls).  A flush is triggered when there are enough
            buffered deletes (see {@link #setMaxBufferedDeleteTerms})
            or enough added documents since the last flush, whichever
            is sooner.  For the added documents, flushing is triggered
            either by RAM usage of the documents (see {@link
            #setRAMBufferSizeMB}) or the number of added documents.
            The default is to flush when RAM usage hits 16 MB.  For
            best indexing speed you should flush by RAM usage with a
            large RAM buffer.  Note that flushing just moves the
            internal buffered state in IndexWriter into the index, but
            these changes are not visible to IndexReader until either
            {@link #Commit()} or {@link #close} is called.  A flush may
            also trigger one or more segment merges which by default
            run with a background thread so as not to block the
            addDocument calls (see <a href="#mergePolicy">below</a>
            for changing the {@link MergeScheduler}).<p/>
            <a name="autoCommit"></a>
            <p/>The optional <code>autoCommit</code> argument to the {@link
            #IndexWriter(Directory, boolean, Analyzer) constructors}
            controls visibility of the changes to {@link IndexReader}
            instances reading the same index.  When this is
            <code>false</code>, changes are not visible until {@link
            #Close()} or {@link #Commit()} is called.  Note that changes will still be
            flushed to the {@link Directory} as new files, but are 
            not committed (no new <code>segments_N</code> file is written 
            referencing the new files, nor are the files sync'd to stable storage)
            until {@link #Close()} or {@link #Commit()} is called.  If something
            goes terribly wrong (for example the JVM crashes), then
            the index will reflect none of the changes made since the
            last commit, or the starting state if commit was not called.
            You can also call {@link #Rollback()}, which closes the writer
            without committing any changes, and removes any index
            files that had been flushed but are now unreferenced.
            This mode is useful for preventing readers from refreshing
            at a bad time (for example after you've done all your
            deletes but before you've done your adds).  It can also be
            used to implement simple single-writer transactional
            semantics ("all or none").  You can do a two-phase commit
            by calling {@link #PrepareCommit()}
            followed by {@link #Commit()}. This is necessary when
            Lucene is working with an external resource (for example,
            a database) and both must either commit or rollback the
            transaction.<p/>
            <p/>When <code>autoCommit</code> is <code>true</code> then
            the writer will periodically commit on its own.  [<b>Deprecated</b>: Note that in 3.0, IndexWriter will
            no longer accept autoCommit=true (it will be hardwired to
            false).  You can always call {@link #Commit()} yourself
            when needed]. There is
            no guarantee when exactly an auto commit will occur (it
            used to be after every flush, but it is now after every
            completed merge, as of 2.4).  If you want to force a
            commit, call {@link #Commit()}, or, close the writer.  Once
            a commit has finished, newly opened {@link IndexReader} instances will
            see the changes to the index as of that commit.  When
            running in this mode, be careful not to refresh your
            readers while optimize or segment merges are taking place
            as this can tie up substantial disk space.<p/>
            </summary>
            <summary><p/>Regardless of <code>autoCommit</code>, an {@link
            IndexReader} or {@link Lucene.Net.Search.IndexSearcher} will only see the
            index as of the "point in time" that it was opened.  Any
            changes committed to the index after the reader was opened
            are not visible until the reader is re-opened.<p/>
            <p/>If an index will not have more documents added for a while and optimal search
            performance is desired, then either the full {@link #Optimize() optimize}
            method or partial {@link #Optimize(int)} method should be
            called before the index is closed.<p/>
            <p/>Opening an <code>IndexWriter</code> creates a lock file for the directory in use. Trying to open
            another <code>IndexWriter</code> on the same directory will lead to a
            {@link LockObtainFailedException}. The {@link LockObtainFailedException}
            is also thrown if an IndexReader on the same directory is used to delete documents
            from the index.<p/>
            </summary>
            <summary><a name="deletionPolicy"></a>
            <p/>Expert: <code>IndexWriter</code> allows an optional
            {@link IndexDeletionPolicy} implementation to be
            specified.  You can use this to control when prior commits
            are deleted from the index.  The default policy is {@link
            KeepOnlyLastCommitDeletionPolicy} which removes all prior
            commits as soon as a new commit is done (this matches
            behavior before 2.2).  Creating your own policy can allow
            you to explicitly keep previous "point in time" commits
            alive in the index for some time, to allow readers to
            refresh to the new commit without having the old commit

            filesystems like NFS that do not support "delete on last

            normally relies on. <p/>
            <a name="mergePolicy"></a> <p/>Expert:
            <code>IndexWriter</code> allows you to separately change
            the {@link MergePolicy} and the {@link MergeScheduler}.
            The {@link MergePolicy} is invoked whenever there are
            changes to the segments in the index.  Its role is to
            select which merges to do, if any, and return a {@link
            MergePolicy.MergeSpecification} describing the merges.  It
            also selects merges to do for optimize().  (The default is
            {@link LogByteSizeMergePolicy}.  Then, the {@link
            MergeScheduler} is invoked with the requested merges and
            it decides when and how to run the merges.  The default is
            {@link ConcurrentMergeScheduler}. <p/>
            <a name="OOME"></a><p/><b>NOTE</b>: if you hit an
            OutOfMemoryError then IndexWriter will quietly record this
            fact and block all future segment commits.  This is a
            defensive measure in case any internal state (buffered
            documents and deletions) were corrupted.  Any subsequent
            calls to {@link #Commit()} will throw an
            IllegalStateException.  The only course of action is to
            call {@link #Close()}, which internally will call {@link
            #Rollback()}, to undo any changes to the index since the
            last commit.  If you opened the writer with autoCommit
            false you can also just call {@link #Rollback()}
            directly.<p/>
            <a name="thread-safety"></a><p/><b>NOTE</b>: {@link
            <code>IndexWriter</code>} instances are completely thread
            safe, meaning multiple threads can call any of its
            methods, concurrently.  If your application requires
            external synchronization, you should <b>not</b>
            synchronize on the <code>IndexWriter</code> instance as
            this may cause deadlock; use your own (non-Lucene) objects

            quickly made available for searching without closing the writer nor
            calling {@link #commit}.
            
            <p/>
            Note that this is functionally equivalent to calling {#commit} and then
            using {@link IndexReader#open} to open a new reader. But the turarnound
            time of this method should be faster since it avoids the potentially
            costly {@link #commit}.

            <p/>
            It's <i>near</i> real-time because there is no hard

            making changes with IndexWriter.  You'll have to

            deletes, etc.  This means additional resources (RAM,
            file descriptors, CPU time) will be consumed.<p/>
            
            <p/>For lower latency on reopening a reader, you may
            want to call {@link #setMergedSegmentWarmer} to

            random-access to terms.
            
            This parameter determines the amount of computation required per query
            term, regardless of the number of documents that contain that term.  In

            by the processing of frequency and positional data.  In a small index
            or when many uncommon query terms are generated (e.g., by wildcard
            queries) term lookup may become a dominant cost.

            deletions is only approximate.  Specifically, if you
            delete by Query, Lucene currently has no way to measure
            the RAM usage if individual Queries so the accounting
            will under-estimate and you should compensate by either
            calling commit() periodically yourself, or by using
            {@link #setMaxBufferedDeleteTerms} to flush by count
            instead of RAM usage (each buffered delete Query counts
            as one).
            
            <p/>
            <b>NOTE</b>: because IndexWriter uses <code>int</code>s when managing its
            internal storage, the absolute maximum value for this setting is somewhat
            less than 2048 MB. The precise limit depends on various factors, such as

        <member name="M:Lucene.Net.Index.IndexWriter.Optimize">
            <summary> Requests an "optimize" operation on an index, priming the index
            for the fastest available search. Traditionally this has meant
            merging all segments into a single segment as is done in the
            default merge policy, but individaul merge policies may implement
            optimize in different ways.
            
            <p/>It is recommended that this method be called upon completion of indexing.  In
            environments with frequent updates, optimize is best done during low volume times, if at all. 
            
            <p/>
            <p/>See http://www.gossamer-threads.com/lists/lucene/java-dev/47895 for more discussion. <p/>
            
            <p/>Note that optimize requires 2X the index size free
            space in your Directory.  For example, if your index
            size is 10 MB then you need 20 MB free for optimize to
            complete.<p/>
            
            <p/>If some but not all readers re-open while an
            optimize is underway, this will cause &gt; 2X temporary
            space to be consumed as those new readers will then
            hold open the partially optimized segments at that
            time.  It is best not to re-open readers while optimize
            is running.<p/>
            
            <p/>The actual temporary usage could be much less than
            these figures (it depends on many factors).<p/>
            
            <p/>In general, once the optimize completes, the total size of the
            index will be less than the size of the starting index.
            It could be quite a bit smaller (if there were many
            pending deletes) or just slightly smaller.<p/>
            
            <p/>If an Exception is hit during optimize(), for example
            due to disk full, the index will not be corrupt and no
            documents will have been lost.  However, it may have
            been partially optimized (some segments were merged but
            not all), and it's possible that one of the segments in
            the index will be in non-compound format even when
            using compound file format.  This will occur when the
            Exception is hit during conversion of the segment into
            compound format.<p/>
            
            <p/>This call will optimize those segments present in
            the index when the call started.  If other threads are
            still adding documents and flushing segments, those
            newly created segments will not be optimized unless you
            call optimize again.<p/>

            <summary>Expunges all deletes from the index.  When an index
            has many document deletions (or updates to existing
            documents), it's best to either call optimize or
            expungeDeletes to remove all unused data in the index
            associated with the deleted documents.  To see how
            many deletions you have pending in your index, call
            {@link IndexReader#numDeletedDocs}
            This saves disk space and memory usage while
            searching.  expungeDeletes should be somewhat faster
            than optimize since it does not insist on reducing the
            index to a single segment (though, this depends on the
            {@link MergePolicy}; see {@link
            MergePolicy#findMergesToExpungeDeletes}.). Note that
            this call does not first commit any buffered

            commitUserData Map (String -> String).  This does the
            first phase of 2-phase commit.  You can only call this
            when autoCommit is false.  This method does all steps
            necessary to commit changes since this writer was
            opened: flushes pending added and deleted docs, syncs
            the index files, writes most of next segments_N file.
            After calling this you must call either {@link
            #Commit()} to finish the commit, or {@link
            #Rollback()} to revert the commit and undo all changes
            done since the writer was opened.<p/>
            
            You can also just call {@link #Commit(Map)} directly
            without prepareCommit first in which case that method
            will internally call prepareCommit.

            index files, such that a reader will see the changes
            and the index updates will survive an OS or machine
            crash or power loss.  Note that this does not wait for
            any running background merges to finish.  This may be a
            costly operation, so you should test the cost in your
            application and do it only when really necessary.<p/>

            the index files.  That call should not return until the
            file contents &amp; metadata are on stable storage.  For
            FSDirectory, this calls the OS's fsync.  But, beware:
            some hardware devices may in fact cache writes even
            during fsync, and return before the bits are actually
            on stable storage, to give the appearance of faster
            performance.  If you have such a device, and it does
            not have a battery backup (for example) then on power
            loss it may still lose data.  Lucene cannot guarantee

        <member name="T:Lucene.Net.Index.IndexReader">
            <summary>IndexReader is an abstract class, providing an interface for accessing an
            index.  Search of an index is done entirely through this abstract interface,
            so that any subclass which implements it is searchable.
            <p/> Concrete subclasses of IndexReader are usually constructed with a call to
            one of the static <code>open()</code> methods, e.g. {@link
            #Open(String, boolean)}.
            <p/> For efficiency, in this API documents are often referred to via
            <i>document numbers</i>, non-negative integers which each name a unique
            document in the index.  These document numbers are ephemeral--they may change
            as documents are added to and deleted from an index.  Clients should thus not
            rely on a given document having the same number between sessions.
            <p/> An IndexReader can be opened on a directory for which an IndexWriter is
            opened already, but it cannot be used to delete documents from the index then.
            <p/>
            <b>NOTE</b>: for backwards API compatibility, several methods are not listed 
            as abstract, but have no useful implementations in this base class and 
            instead always throw UnsupportedOperationException.  Subclasses are 
            strongly encouraged to override these methods, but in many cases may not 
            need to.
            <p/>
            <p/>
            <b>NOTE</b>: as of 2.4, it's possible to open a read-only
            IndexReader using one of the static open methods that
            accepts the boolean readOnly parameter.  Such a reader has
            better concurrency as it's not necessary to synchronize on
            the isDeleted method.  Currently the default for readOnly
            is false, meaning if not specified you will get a
            read/write IndexReader.  But in 3.0 this default will
            change to true, meaning you must explicitly specify false
            if you want to make changes with the resulting IndexReader.
            <p/>
            <a name="thread-safety"></a><p/><b>NOTE</b>: {@link
            <code>IndexReader</code>} instances are completely thread
            safe, meaning multiple threads can call any of its methods,
            concurrently.  If your application requires external
            synchronization, you should <b>not</b> synchronize on the
            <code>IndexReader</code> instance; use your own
            (non-Lucene) objects instead.

            <summary> Refreshes an IndexReader if the index has changed since this instance 
            was (re)opened. 
            <p/>
            Opening an IndexReader is an expensive operation. This method can be used
            to refresh an existing IndexReader to reduce these costs. This method 
            tries to only load segments that have changed or were created after the 
            IndexReader was (re)opened.
            <p/>
            If the index has not changed since this instance was (re)opened, then this
            call is a NOOP and returns this instance. Otherwise, a new instance is 
            returned. The old instance is <b>not</b> closed and remains usable.<br/>
            <p/>   
            If the reader is reopened, even though they share
            resources internally, it's safe to make changes
            (deletions, norms) with the new reader.  All shared
            mutable state obeys "copy on write" semantics to ensure
            the changes are not seen by other readers.
            <p/>
            You can determine whether a reader was actually reopened by comparing the
            old instance with the instance returned by this method: 
            <pre>
            IndexReader reader = ... 
            ...
            IndexReader newReader = r.reopen();
            if (newReader != reader) {
            ...     // reader was reopened
            reader.close(); 
            }
            reader = newReader;
            ...
            </pre>
            
            Be sure to synchronize that code so that other threads,
            if present, can never use reader after it has been
            closed and before it's switched to newReader.
            
            <p/><b>NOTE</b>: If this reader is a near real-time
            reader (obtained from {@link IndexWriter#GetReader()},

            you, though this may change in the future.

            On cloning a reader with pending changes (deletions,
            norms), the original reader transfers its write lock to
            the cloned reader.  This means only the cloned reader
            may make further changes to the index, and commit the
            changes to the index on close, but the old reader still
            reflects all changes made up until it was cloned.
            <p/>
            Like {@link #Reopen()}, it's safe to make changes to
            either the original or the cloned reader: all shared

            <p/>To quickly execute range queries in Apache Lucene, a range is divided recursively
            into multiple intervals for searching: The center of the range is searched only with
            the lowest possible precision in the trie, while the boundaries are matched
            more exactly. This reduces the number of terms dramatically.
            
            <p/>This class generates terms to achive this: First the numerical integer values need to
            be converted to strings. For that integer values (32 bit or 64 bit) are made unsigned
            and the bits are converted to ASCII chars with each 7 bit. The resulting string is
            sortable like the original integer value. Each value is also prefixed
            (in the first char) by the <code>shift</code> value (number of bits removed) used
            during encoding.
            
            <p/>To also index floating point numbers, this class supplies two methods to convert them
            to integer values by changing their bit layout: {@link #doubleToSortableLong},
            {@link #floatToSortableInt}. You will have no precision loss by
            converting floating point numbers to integers and back (only that the integer form
            is not usable). Other data types like dates can easily converted to longs or ints (e.g.
            date to long: {@link java.util.Date#getTime}).
            
            <p/>For easy usage, the trie algorithm is implemented for indexing inside
            {@link NumericTokenStream} that can index <code>int</code>, <code>long</code>,
            <code>float</code>, and <code>double</code>. For querying,
            {@link NumericRangeQuery} and {@link NumericRangeFilter} implement the query part
            for the same data types.
            
            <p/>This class can also be used, to generate lexicographically sortable (according
            {@link String#compareTo(String)}) representations of numeric data types for other
            usages (e.g. sorting).

            <br/>A document is considered matching if it contains the phrase-query terms  
            at "valid" positons. What "valid positions" are
            depends on the type of the phrase query: for an exact phrase query terms are required 
            to appear in adjacent locations, while for a sloppy phrase query some distance between 
            the terms is allowed. The abstract method {@link #PhraseFreq()} of extending classes
            is invoked for each document containing all the phrase query terms, in order to 
            compute the frequency of the phrase query in that document. A non zero frequency

            <p/>Not all methods of IndexReader and IndexWriter are offered by this
            class. If you need access to additional methods, either use those classes
            directly or implement your own class that extends <code>IndexModifier</code>.
            
            <p/>Although an instance of this class can be used from more than one
            thread, you will not get the best performance. You might want to use
            IndexReader and IndexWriter directly for that (but you will need to
            care about synchronization yourself then).
            
            <p/>While you can freely mix calls to add() and delete() using this class,
            you should batch you calls for best performance. For example, if you
            want to update 20 documents, you should first delete all those documents,
            then add all the new documents.

            <summary> <b>Expert:</b> This class provides a {@link TokenStream}
            for indexing numeric values that can be used by {@link
            NumericRangeQuery} or {@link NumericRangeFilter}.
            
            <p/>Note that for simple usage, {@link NumericField} is
            recommended.  {@link NumericField} disables norms and
            term freqs, as they are not usually needed during
            searching.  If you need to change these settings, you
            should use this class.
            
            <p/>See {@link NumericField} for capabilities of fields
            indexed numerically.<p/>
            
            <p/>Here's an example usage, for an <code>int</code> field:
            
            <pre>
             Field field = new Field(name, new NumericTokenStream(precisionStep).setIntValue(value));
             field.setOmitNorms(true);
             field.setOmitTermFreqAndPositions(true);
             document.add(field);
            </pre>
            
            <p/>For optimal performance, re-use the TokenStream and Field instance
            for more than one document:
            
            <pre>
             NumericTokenStream stream = new NumericTokenStream(precisionStep);
             Field field = new Field(name, stream);
             field.setOmitNorms(true);
             field.setOmitTermFreqAndPositions(true);
             Document document = new Document();
             document.add(field);
            
             for(all documents) {
               stream.setIntValue(value)
               writer.addDocument(document);
             }
            </pre>
            
            <p/>This stream is not intended to be used in analyzers;
            it's more for iterating the different precisions during
            indexing a specific numeric value.<p/>
            
            <p/><b>NOTE</b>: as token streams are only consumed once
            the document is added to the index, if you index more
            than one numeric field, use a separate <code>NumericTokenStream</code>
            instance for each.<p/>
            
            <p/>See {@link NumericRangeQuery} for more details on the

            similarity = 1 - ((float)distance / (float) (prefixLength + Math.min(textlen, targetlen)));

            <summary> <p/>Expert: policy for deletion of stale {@link IndexCommit index commits}. 
            
            <p/>Implement this interface, and pass it to one
            of the {@link IndexWriter} or {@link IndexReader}
            constructors, to customize when older
            {@link IndexCommit point-in-time commits}
            are deleted from the index directory.  The default deletion policy
            is {@link KeepOnlyLastCommitDeletionPolicy}, which always
            removes old commits as soon as a new commit is done (this
            matches the behavior before 2.2).<p/>
            
            <p/>One expected use case for this (and the reason why it
            was first created) is to work around problems with an
            index directory accessed via filesystems like NFS because
            NFS does not provide the "delete on last close" semantics
            that Lucene's "point in time" search normally relies on.
            By implementing a custom deletion policy, such as "a
            commit is only removed once it has been stale for more
            than X minutes", you can give your readers time to
            refresh to the new commit before {@link IndexWriter}
            removes the old commits.  Note that doing so will
            increase the storage requirements of the index.  See <a

            <p/><b>NOTE:</b> the <a target="_top" href="http://java.sun.com/j2se/1.4.2/docs/api/java/io/File.html#createNewFile()">javadocs
            for <code>File.createNewFile</code></a> contain a vague
            yet spooky warning about not using the API for file
            locking.  This warning was added due to <a target="_top" href="http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4676183">this
            bug</a>, and in fact the only known problem with using
            this API for locking is that the Lucene write lock may
            not be released when the JVM exits abnormally.<p/>
            <p/>When this happens, a {@link LockObtainFailedException}
            is hit when trying to create a writer, in which case you
            need to explicitly clear the lock file first.  You can
            either manually remove the file, or use the {@link
            org.apache.lucene.index.IndexReader#unlock(Directory)}
            API.  But, first be certain that no writer is in fact
            writing to the index otherwise you can easily corrupt
            your index.<p/>
            
            <p/>If you suspect that this or any other LockFactory is
            not working properly in your environment, you can easily
            test it by using {@link VerifyingLockFactory}, {@link

            However the resulted <i>norm</i> value is {@link #EncodeNorm(float) encoded} as a single byte
            before being stored.
            At search time, the norm byte value is read from the index
            {@link Lucene.Net.Store.Directory directory} and
            {@link #DecodeNorm(byte) decoded} back to a float <i>norm</i> value.
            This encoding/decoding, while reducing index size, comes with the price of
            precision loss - it is not guaranteed that decode(encode(x)) = x.
            For instance, decode(encode(0.89)) = 0.75.
            Also notice that search time is too late to modify this <i>norm</i> part of scoring, e.g. by
            using a different {@link Similarity} for search.

            being returned, rather than every matching hit.
            
            <b>NOTE:</b> this interface is kept public for convenience. Since it is not

            and will be merged whenever there are mergeFactor of
            them.  This effectively truncates the "long tail" of
            small segments that would otherwise be created into a
            single level.  If you set this too large, it could
            greatly increase the merging cost during indexing (if
            you flush many small segments).

            This class will be used as part of a key to a FieldCache value. You must
            implement hashCode and equals to avoid an explosion in RAM usage if you use
            instances that are not the same instance. If you are searching using the
            Remote contrib, the same instance of this class on the client will be a new
            instance on every call to the server, so hashCode/equals is very important in
            that situation.

            best to switch your application to pass only atomic
            (single segment) readers to this API.  Alternatively, for
            a short-term fix, you could wrap your ValueSource using
            {@link MultiValueSource}, which costs more CPU per lookup
            but will not consume double the FieldCache RAM.<p/>

        <member name="T:Lucene.Net.Index.DocumentsWriter">
            <summary> This class accepts multiple added documents and directly
            writes a single segment file.  It does this more
            efficiently than creating a single segment per document
            (with DocumentWriter) and doing standard merges on those
            segments.
            
            Each added document is passed to the {@link DocConsumer},
            which in turn processes the document and interacts with
            other consumers in the indexing chain.  Certain
            consumers, like {@link StoredFieldsWriter} and {@link
            TermVectorsTermsWriter}, digest a document and
            immediately write bytes to the "doc store" files (ie,
            they do not consume RAM per document, except while they
            are processing the document).
            
            Other consumers, eg {@link FreqProxTermsWriter} and
            {@link NormsWriter}, buffer bytes in RAM and flush only
            when a new segment is produced.
            Once we have used our allowed RAM buffer, or the number
            of added docs is large enough (in the case we are
            flushing by doc count instead of RAM usage), we create a
            real segment and flush it to the Directory.
            
            Threads:
            
            Multiple threads are allowed into addDocument at once.
            There is an initial synchronized call to getThreadState
            which allocates a ThreadState for this thread.  The same
            thread will get the same ThreadState over time (thread
            affinity) so that if there are consistent patterns (for
            example each thread is indexing a different content
            source) then we make better use of RAM.  Then
            processDocument is called on that ThreadState without
            synchronization (most of the "heavy lifting" is in this
            call).  Finally the synchronized "finishDocument" is
            called to flush changes to the directory.
            
            When flush is called by IndexWriter, or, we flush
            internally when autoCommit=false, we forcefully idle all
            threads and flush only once they are all idle.  This
            means you can call flush with a given thread even while
            other threads are actively adding/deleting documents.
            
            
            Exceptions:
            
            Because this class directly updates in-memory posting
            lists, and flushes stored fields and term vectors
            directly to files in the directory, there are certain
            limited times when an exception can corrupt this state.
            For example, a disk full while flushing stored fields
            leaves this file in a corrupt state.  Or, an OOM
            exception while appending to the in-memory posting lists
            can corrupt that posting list.  We call such exceptions
            "aborting exceptions".  In these cases we must call
            abort() to discard all docs added since the last flush.
            
            All other exceptions ("non-aborting exceptions") can
            still partially update the index structures.  These
            updates are consistent, but, they represent only a part
            of the document seen up until the exception was hit.
            When this happens, we immediately mark the document as
            deleted so that the document is always atomically ("all
            or none") added to the index.

            <summary> Provides support for converting byte sequences to Strings and back again.
            The resulting Strings preserve the original byte sequences' sort order.
            
            The Strings are constructed using a Base 8000h encoding of the original
            binary data - each char of an encoded String represents a 15-bit chunk
            from the byte sequence.  Base 8000h was chosen because it allows for all
            lower 15 bits of char to be used without restriction; the surrogate range 
            [U+D8000-U+DFFF] does not represent valid chars, and would require
            complicated handling to avoid them and allow use of char's high bit.
            
            Although unset bits are used as padding in the final char, the original
            byte sequence could contain trailing bytes with no set bits (null bytes):
            padding is indistinguishable from valid information.  To overcome this
            problem, a char is appended, indicating the number of encoded bytes in the
            final content char.
            
            This class's operations are defined over CharBuffers and ByteBuffers, to
            allow for wrapped arrays to be reused, reducing memory allocation costs for
            repeated operations.  Note that this class calls array() and arrayOffset()
            on the CharBuffers and ByteBuffers it uses, so only wrapped arrays may be
            used.  This class interprets the arrayOffset() and limit() values returned by
            its input buffers as beginning and end+1 positions on the wrapped array,
            resprectively; similarly, on the output buffer, arrayOffset() is the first
            position written to, and limit() is set to one past the final output array
            position.

            <p/>
            The native lucene index order is used to assign an ordinal value for each field value.
            <p/>
            Field values (terms) are lexicographically ordered by unicode value, and numbered starting at 1.
            <p/>
            Example:
            <br/>If there were only three field values: "apple","banana","pear"
            <br/>then ord("apple")=1, ord("banana")=2, ord("pear")=3
            <p/>
            WARNING: 
            ord() depends on the position in an index and can thus change 
            when other documents are inserted or deleted,
            or if a MultiSearcher is used.

            <summary> A query that scores each document as the value of the numeric input field.
            <p/> 
            The query matches all documents, and scores each document according to the numeric 
            value of that field. 
            <p/>
            It is assumed, and expected, that:
            <ul>
            <li>The field used here is indexed, and has exactly 
            one token in every scored document.</li> 
            <li>Best if this field is un_tokenized.</li>
            <li>That token is parsable to the selected type.</li>
            </ul>
            <p/>  
            Combining this query in a FunctionQuery allows much freedom in affecting document scores.
            Note, that with this freedom comes responsibility: it is more than likely that the
            default Lucene scoring is superior in quality to scoring modified as explained here.
            However, in some cases, and certainly for research experiments, this capability may turn useful.
            <p/>
            When contructing this query, select the appropriate type. That type should match the data stored in the
            field. So in fact the "right" type should be selected before indexing. Type selection
            has effect on the RAM usage: 
            <ul>
            <li>{@link Type#BYTE} consumes 1 * maxDocs bytes.</li>
            <li>{@link Type#SHORT} consumes 2 * maxDocs bytes.</li>
            <li>{@link Type#INT} consumes 4 * maxDocs bytes.</li>
            <li>{@link Type#FLOAT} consumes 8 * maxDocs bytes.</li>
            </ul>
            <p/>
            <b>Caching:</b>
            Values for the numeric field are loaded once and cached in memory for further use with the same IndexReader. 
            To take advantage of this, it is extremely important to reuse index-readers or index-searchers, 
            otherwise, for instance if for each query a new index reader is opened, large penalties would be 
            paid for loading the field values into memory over and over again!

            Base class for Directory implementations that store index
            files in the file system.  There are currently three core
            subclasses:
            
            <ul>
            
            <li> {@link SimpleFSDirectory} is a straightforward
            implementation using java.io.RandomAccessFile.
            However, it has poor concurrent performance
            (multiple threads will bottleneck) as it
            synchronizes when multiple threads read from the
            same file.</li>
            
            <li> {@link NIOFSDirectory} uses java.nio's
            FileChannel's positional io when reading to avoid
            synchronization when reading from the same file.
            Unfortunately, due to a Windows-only <a href="http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6265734">Sun
            JRE bug</a> this is a poor choice for Windows, but
            on all other platforms this is the preferred
            choice.</li>
            
            <li> {@link MMapDirectory} uses memory-mapped IO when
            reading. This is a good choice if you have plenty
            of virtual memory relative to your index size, eg
            if you are running on a 64 bit JRE, or you are
            running on a 32 bit JRE but your index sizes are
            small enough to fit into the virtual memory space.
            Java has currently the limitation of not being able to
            unmap files from user code. The files are unmapped, when GC
            releases the byte buffers. Due to
            <a href="http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4724038">
            this bug</a> in Sun's JRE, MMapDirectory's {@link IndexInput#close}
            is unable to close the underlying OS file handle. Only when
            GC finally collects the underlying objects, which could be
            quite some time later, will the file handle be closed.
            This will consume additional transient disk usage: on Windows,
            attempts to delete or overwrite the files will result in an
            exception; on other platforms, which typically have a "delete on
            last close" semantics, while such operations will succeed, the bytes
            are still consuming space on disk.  For many applications this
            limitation is not a problem (e.g. if you have plenty of disk space,
            and you don't rely on overwriting files on Windows) but it's still
            an important limitation to be aware of. This class supplies a
            (possibly dangerous) workaround mentioned in the bug report,
            which may fail on non-Sun JVMs.</li>
            </ul>
            
            Unfortunately, because of system peculiarities, there is
            no single overall best implementation.  Therefore, we've
            added the {@link #open} method, to allow Lucene to choose
            the best FSDirectory implementation given your
            environment, and the known limitations of each
            implementation.  For users who have no reason to prefer a
            specific implementation, it's best to simply use {@link
            #open}.  For all others, you should instantiate the
            desired implementation directly.
            
            <p/>The locking implementation is by default {@link
            NativeFSLockFactory}, but can be changed by
            passing in a custom {@link LockFactory} instance.
            The deprecated <code>getDirectory</code> methods default to use
            {@link SimpleFSLockFactory} for backwards compatibility.
            The system properties 
            <code>org.apache.lucene.store.FSDirectoryLockFactoryClass</code>
            and <code>org.apache.lucene.FSDirectory.class</code>
            are deprecated and only used by the deprecated
            <code>getDirectory</code> methods. The system property
            <code>org.apache.lucene.lockDir</code> is ignored completely,
            If you really want to store locks
            elsewhere, you can create your own {@link
            SimpleFSLockFactory} (or {@link NativeFSLockFactory},
            etc.) passing in your preferred lock directory.

            <p/>
            Background: although the contract of the Scorer class requires that
            documents be iterated in order of doc id, this was not true in early
            versions of Lucene. Many pieces of functionality in the current Lucene code
            base have undefined behavior if this contract is not upheld, but in some
            specific simple cases may be faster. (For example: disjunction queries with
            less than 32 prohibited clauses; This setting has no effect for other
            queries.)
            <p/>
            
            <p/>
            Specifics: By setting this option to true, docid N might be scored for a
            single segment before docid N-1. Across multiple segments, docs may be
            scored out of order regardless of this setting - it only applies to scoring
            a single segment.
            
            Being static, this setting is system wide.

            <summary>Java's builtin ThreadLocal has a serious flaw:
            it can take an arbitrarily long amount of time to
            dereference the things you had stored in it, even once the
            ThreadLocal instance itself is no longer referenced.
            This is because there is single, master map stored for
            each thread, which all ThreadLocals share, and that
            master map only periodically purges "stale" entries.
            
            While not technically a memory leak, because eventually
            the memory will be reclaimed, it can take a long time
            and you can easily hit OutOfMemoryError because from the
            GC's standpoint the stale entries are not reclaimaible.
            
            This class works around that, by only enrolling
            WeakReference values into the ThreadLocal, and
            separately holding a hard reference to each stored
            value.  When you call {@link #close}, these hard
            references are cleared and then GC is freely able to
            reclaim space by objects stored in it.

            <br/> The score contribution of a match depends on the distance: 
            <br/> - highest score for distance=0 (exact match).
            <br/> - score gets lower as distance gets higher.
            <br/>Example: for query "a b"~2, a document "x a b a y" can be scored twice:

            we always propagate the least PhrasePosition. This allows to base on 
            PriorityQueue and move forward faster. 
            As result, for example, document "a b c b a"
            would score differently for queries "a b c"~4 and "c b a"~4, although

            <summary> <p/>A {@link Query} that matches numeric values within a
            specified range.  To use this, you must first index the
            numeric values using {@link NumericField} (expert: {@link
            NumericTokenStream}).  If your terms are instead textual,
            you should use {@link TermRangeQuery}.  {@link
            NumericRangeFilter} is the filter equivalent of this
            query.<p/>
            
            <p/>You create a new NumericRangeQuery with the static
            factory methods, eg:
            
            <pre>
            Query q = NumericRangeQuery.newFloatRange("weight",
            new Float(0.3f), new Float(0.10f),
            true, true);
            </pre>
            
            matches all documents whose float valued "weight" field
            ranges from 0.3 to 0.10, inclusive.
            
            <p/>The performance of NumericRangeQuery is much better
            than the corresponding {@link TermRangeQuery} because the
            number of terms that must be searched is usually far
            fewer, thanks to trie indexing, described below.<p/>

            when creating this query.  This is necessary if you've
            changed this configuration from its default (4) during
            indexing.  Lower values consume more disk space but speed
            up searching.  Suitable values are between <b>1</b> and
            <b>8</b>. A good starting point to test is <b>4</b>,
            which is the default value for all <code>Numeric*</code>
            classes.  See <a href="#precisionStepDesc">below</a> for
            details.
            
            <p/>This query defaults to {@linkplain
            MultiTermQuery#CONSTANT_SCORE_AUTO_REWRITE_DEFAULT} for
            32 bit (int/float) ranges with precisionStep &lt;8 and 64
            bit (long/double) ranges with precisionStep &lt;6.
            Otherwise it uses {@linkplain
            MultiTermQuery#CONSTANT_SCORE_FILTER_REWRITE} as the
            number of terms is likely to be high.  With precision
            steps of &lt;4, this query can be run with one of the
            BooleanQuery rewrite methods without changing
            BooleanQuery's default max clause count.

            <p/>See the publication about <a target="_blank" href="http://www.panfmp.org">panFMP</a>,
            where this algorithm was described (referred to as <code>TrieRangeQuery</code>):
            
            <blockquote><strong>Schindler, U, Diepenbroek, M</strong>, 2008.

            <p/><em>A quote from this paper:</em> Because Apache Lucene is a full-text
            search engine and not a conventional database, it cannot handle numerical ranges
            (e.g., field value is inside user defined bounds, even dates are numerical values).
            We have developed an extension to Apache Lucene that stores
            the numerical values in a special string-encoded format with variable precision
            (all numerical values like doubles, longs, floats, and ints are converted to
            lexicographic sortable string representations and stored with different precisions
            (for a more detailed description of how the values are stored,
            see {@link NumericUtils}). A range is then divided recursively into multiple intervals for searching:
            The center of the range is searched only with the lowest possible precision in the <em>trie</em>,
            while the boundaries are matched more exactly. This reduces the number of terms dramatically.<p/>
            
            <p/>For the variant that stores long values in 8 different precisions (each reduced by 8 bits) that
            uses a lowest precision of 1 byte, the index contains only a maximum of 256 distinct values in the
            lowest precision. Overall, a range could consist of a theoretical maximum of
            <code>7*255*2 + 255 = 3825</code> distinct terms (when there is a term for every distinct value of an
            8-byte-number in the index and the range covers almost all of them; a maximum of 255 distinct values is used
            because it would always be possible to reduce the full 256 values to one term with degraded precision).
            In practice, we have seen up to 300 terms in most cases (index with 500,000 metadata records
            and a uniform value distribution).<p/>
            
            <a name="precisionStepDesc"/><h3>Precision Step</h3>
            <p/>You can choose any <code>precisionStep</code> when encoding values.
            Lower step values mean more precisions and so more terms in index (and index gets larger).
            On the other hand, the maximum number of terms to match reduces, which optimized query speed.
            The formula to calculate the maximum term count is:
            <pre>
            n = [ (bitsPerValue/precisionStep - 1) * (2^precisionStep - 1 ) * 2 ] + (2^precisionStep - 1 )
            </pre>
            <p/><em>(this formula is only correct, when <code>bitsPerValue/precisionStep</code> is an integer;
            in other cases, the value must be rounded up and the last summand must contain the modulo of the division as
            precision step)</em>.
            For longs stored using a precision step of 4, <code>n = 15*15*2 + 15 = 465</code>, and for a precision
            step of 2, <code>n = 31*3*2 + 3 = 189</code>. But the faster search speed is reduced by more seeking
            in the term enum of the index. Because of this, the ideal <code>precisionStep</code> value can only
            be found out by testing. <b>Important:</b> You can index with a lower precision step value and test search speed
            using a multiple of the original step value.<p/>
            
            <p/>Good values for <code>precisionStep</code> are depending on usage and data type:
            <ul>
            <li>The default for all data types is <b>4</b>, which is used, when no <code>precisionStep</code> is given.</li>
            <li>Ideal value in most cases for <em>64 bit</em> data types <em>(long, double)</em> is <b>6</b> or <b>8</b>.</li>
            <li>Ideal value in most cases for <em>32 bit</em> data types <em>(int, float)</em> is <b>4</b>.</li>
            <li>Steps <b>&gt;64</b> for <em>long/double</em> and <b>&gt;32</b> for <em>int/float</em> produces one token
            per value in the index and querying is as slow as a conventional {@link TermRangeQuery}. But it can be used
            to produce fields, that are solely used for sorting (in this case simply use {@link Integer#MAX_VALUE} as
            <code>precisionStep</code>). Using {@link NumericField NumericFields} for sorting
            is ideal, because building the field cache is much faster than with text-only numbers.
            Sorting is also possible with range query optimized fields using one of the above <code>precisionSteps</code>.</li>
            </ul>
            
            <p/>Comparisons of the different types of RangeQueries on an index with about 500,000 docs showed
            that {@link TermRangeQuery} in boolean rewrite mode (with raised {@link BooleanQuery} clause count)
            took about 30-40 secs to complete, {@link TermRangeQuery} in constant score filter rewrite mode took 5 secs
            and executing this class took &lt;100ms to complete (on an Opteron64 machine, Java 1.5, 8 bit
            precision step). This query type was developed for a geographic portal, where the performance for
            e.g. bounding boxes or exact date/time stamps is important.<p/>

            <summary> A query that generates the union of documents produced by its subqueries, and that scores each document with the maximum
            score for that document as produced by any subquery, plus a tie breaking increment for any additional matching subqueries.
            This is useful when searching for a word in multiple fields with different boost factors (so that the fields cannot be
            combined equivalently into a single search field).  We want the primary score to be the one associated with the highest boost,
            not the sum of the field scores (as BooleanQuery would give).
            If the query is "albino elephant" this ensures that "albino" matching one field and "elephant" matching
            another gets a higher score than "albino" matching both fields.
            To get this result, use both BooleanQuery and DisjunctionMaxQuery:  for each term a DisjunctionMaxQuery searches for it in
            each field, while the set of these DisjunctionMaxQuery's is combined into a BooleanQuery.
            The tie breaker capability allows results that include the same term in multiple fields to be judged better than results that
            include this term in only the best of those multiple fields, without confusing this with the better case of two different terms
            in the multiple fields.

            <summary> A {@link Filter} that only accepts documents whose single
            term value in the specified field is contained in the
            provided set of allowed terms.
            
            <p/>
            
            This is the same functionality as TermsFilter (from
            contrib/queries), except this filter requires that the
            field contains only a single term for all documents.
            Because of drastically different implementations, they
            also have different performance characteristics, as
            described below.
            
            <p/>
            
            The first invocation of this filter on a given field will
            be slower, since a {@link FieldCache.StringIndex} must be
            created.  Subsequent invocations using the same field
            will re-use this cache.  However, as with all
            functionality based on {@link FieldCache}, persistent RAM
            is consumed to hold the cache, and is not freed until the
            {@link IndexReader} is closed.  In contrast, TermsFilter
            has no persistent RAM consumption.
            
            
            <p/>
            
            With each search, this filter translates the specified
            set of Terms into a private {@link OpenBitSet} keyed by
            term number per unique {@link IndexReader} (normally one
            reader per segment).  Then, during matching, the term
            number for each docID is retrieved from the cache and
            then checked for inclusion using the {@link OpenBitSet}.
            Since all testing is done using RAM resident data
            structures, performance should be very fast, most likely
            fast enough to not require further caching of the
            DocIdSet for each possible combination of terms.
            However, because docIDs are simply scanned linearly, an
            index with a great many small documents may find this
            linear scan too costly.
            
            <p/>
            
            In contrast, TermsFilter builds up an {@link OpenBitSet},
            keyed by docID, every time it's created, by enumerating
            through all matching docs using {@link TermDocs} to seek
            and scan through each term's docID list.  While there is
            no linear scan of all docIDs, besides the allocation of
            the underlying array in the {@link OpenBitSet}, this
            approach requires a number of "disk seeks" in proportion
            to the number of terms, which can be exceptionally costly
            when there are cache misses in the OS's IO cache.
            
            <p/>
            
            Generally, this filter will be slower on the first
            invocation for a given field, but subsequent invocations,
            even if you change the allowed set of Terms, should be
            faster than TermsFilter, especially as the number of
            Terms being matched increases.  If you are matching only
            a very small number of terms, and those terms in turn
            match a very small number of documents, TermsFilter may
            perform faster.
            
            <p/>
            
            Which filter is best is very application dependent.

            This class should only be used if the other SortField types (SCORE, DOC,
            STRING, INT, FLOAT) do not provide an adequate sorting. It maintains an
            internal cache of values which could be quite large. The cache is an array of
            Comparable, one for each document in the index. There is a distinct
            Comparable for each unique term in the field - if some documents have the
            same term in the field, the cache array will have entries which reference the
            same Comparable.
            
            This class will be used as part of a key to a FieldCache value. You must
            implement hashCode and equals to avoid an explosion in RAM usage if you use
            instances that are not the same instance. If you are searching using the
            Remote contrib, the same instance of this class on the client will be a new
            instance on every call to the server, so hashCode/equals is very important in
            that situation.

            sorting, by exposing a tight interaction with {@link
            FieldValueHitQueue} as it visits hits.  Whenever a hit is
            competitive, it's enrolled into a virtual slot, which is
            an int ranging from 0 to numHits-1.  The {@link

            during searching in case any internal state it's tracking
            needs to be recomputed during these transitions.<p/>

            <ul>
            
            <li> {@link #compare} Compare a hit at 'slot a'

            {@link FieldValueHitQueue} to notify the
            FieldComparator of the current weakest ("bottom")
            slot.  Note that this slot may not hold the weakest
            value according to your comparator, in cases where
            your comparator is not the primary one (ie, is only
            used to break ties from the comparators before it).</li>

            priority queue.  The {@link FieldValueHitQueue}
            calls this method when a new hit is competitive.</li>
            
            <li> {@link #setNextReader} Invoked
            when the search is switching to the next segment.
            You may need to update internal state of the

        <member name="T:Lucene.Net.QueryParsers.QueryParser">
            <summary> This class is generated by JavaCC.  The most important method is
            {@link #Parse(String)}.
            
            The syntax for query strings is as follows:
            A Query is a series of clauses.
            A clause may be prefixed by:
            <ul>
            <li> a plus (<code>+</code>) or a minus (<code>-</code>) sign, indicating
            that the clause is required or prohibited respectively; or</li>
            <li> a term followed by a colon, indicating the field to be searched.
            This enables one to construct queries which search multiple fields.</li>
            </ul>
            
            A clause may be either:
            <ul>
            <li> a term, indicating all the documents that contain this term; or</li>
            <li> a nested query, enclosed in parentheses.  Note that this may be used
            with a <code>+</code>/<code>-</code> prefix to require any of a set of
            terms.</li>
            </ul>
            
            Thus, in BNF, the query grammar is:
            <pre>
            Query  ::= ( Clause )*
            Clause ::= ["+", "-"] [&lt;TERM&gt; ":"] ( &lt;TERM&gt; | "(" Query ")" )
            </pre>
            
            <p/>
            Examples of appropriately formatted queries can be found in the <a
            href="../../../../../../queryparsersyntax.html">query syntax
            documentation</a>.
            <p/>
            
            <p/>
            In {@link TermRangeQuery}s, QueryParser tries to detect date values, e.g.
            <tt>date:[6/1/2005 TO 6/4/2005]</tt> produces a range query that searches
            for "date" fields between 2005-06-01 and 2005-06-04. Note that the format
            of the accepted input depends on {@link #SetLocale(Locale) the locale}.
            By default a date is converted into a search term using the deprecated
            {@link DateField} for compatibility reasons.
            To use the new {@link DateTools} to convert dates, a
            {@link Lucene.Net.Documents.DateTools.Resolution} has to be set.
            <p/>
            <p/>
            The date resolution that shall be used for RangeQueries can be set
            using {@link #SetDateResolution(DateTools.Resolution)}
            or {@link #SetDateResolution(String, DateTools.Resolution)}. The former
            sets the default date resolution for all fields, whereas the latter can
            be used to set field specific date resolutions. Field specific date
            resolutions take, if set, precedence over the default date resolution.
            <p/>
            <p/>
            If you use neither {@link DateField} nor {@link DateTools} in your
            index, you can create your own
            query parser that inherits QueryParser and overwrites
            {@link #GetRangeQuery(String, String, String, boolean)} to
            use a different method for date conversion.
            <p/>
            
            <p/>Note that QueryParser is <em>not</em> thread-safe.<p/>

            {@link #getWildcardQuery}). Called when parser parses an input term
            token that uses prefix notation; that is, contains a single '*' wildcard
            character as its last character. Since this is a special case
            of generic wildcard term, and such a query can be optimized easily,
            this usually results in a different query object.
            <p/>
            Depending on settings, a prefix term may be lower-cased
            automatically. It will not go through the default Analyzer,
            however, since normal Analyzers are unlikely to work properly
            with wildcard templates.
            <p/>
            Can be overridden by extending classes, to provide custom handling for
            wild card queries, which may be necessary due to missing analyzer calls.

        <member name="T:Lucene.Net.Search.FieldCacheRangeFilter">
            <summary> A range filter built on top of a cached single term field (in {@link FieldCache}).
            
            <p/>FieldCacheRangeFilter builds a single cache for the field the first time it is used.
            Each subsequent FieldCacheRangeFilter on the same field then reuses this cache,
            even if the range itself changes. 
            
            <p/>This means that FieldCacheRangeFilter is much faster (sometimes more than 100x as fast) 
            as building a {@link TermRangeFilter} (or {@link ConstantScoreRangeQuery} on a {@link TermRangeFilter})
            for each query, if using a {@link #newStringRange}. However, if the range never changes it
            is slower (around 2x as slow) than building a CachingWrapperFilter on top of a single TermRangeFilter.
            
            For numeric data types, this filter may be significantly faster than {@link NumericRangeFilter}.
            Furthermore, it does not need the numeric values encoded by {@link NumericField}. But
            it has the problem that it only works with exact one value/document (see below).
            
            <p/>As with all {@link FieldCache} based functionality, FieldCacheRangeFilter is only valid for 
            fields which exact one term for each document (except for {@link #newStringRange}
            where 0 terms are also allowed). Due to a restriction of {@link FieldCache}, for numeric ranges
            all terms that do not have a numeric value, 0 is assumed.
            
            <p/>Thus it works on dates, prices and other single value fields but will not work on
            regular text fields. It is preferable to use a <code>NOT_ANALYZED</code> field to ensure that
            there is only a single term. 
            
            <p/>This class does not have an constructor, use one of the static factory methods available,
            that create a correct instance for different data types supported by {@link FieldCache}.

            in this class take slightly more space, unless your selected resolution
            is set to <code>Resolution.DAY</code> or lower.
            
            <p/>
            Another approach is {@link NumericUtils}, which provides
            a sortable binary representation (prefix encoded) of numeric values, which
            date/time are.
            For indexing a {@link Date} or {@link Calendar}, just get the unix timestamp as
            <code>long</code> using {@link Date#getTime} or {@link Calendar#getTimeInMillis} and
            index this as a numeric value with {@link NumericField}
            and use {@link NumericRangeQuery} to query it.

            <p/><b>NOTE</b>: memory mapping uses up a portion of the
            virtual memory address space in your process equal to the
            size of the file being mapped.  Before using this class,
            be sure your have plenty of virtual address space, e.g. by
            using a 64 bit JRE, or a 32 bit JRE with indexes that are
            guaranteed to fit within the address space.
            On 32 bit platforms also consult {@link #setMaxChunkSize}
            if you have problems with mmap failing because of fragmented
            address space. If you get an OutOfMemoryException, it is recommened

            <p/>Due to <a href="http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4724038">
            this bug</a> in Sun's JRE, MMapDirectory's {@link IndexInput#close}
            is unable to close the underlying OS file handle.  Only when GC
            finally collects the underlying objects, which could be quite
            some time later, will the file handle be closed.
            
            <p/>This will consume additional transient disk usage: on Windows,
            attempts to delete or overwrite the files will result in an
            exception; on other platforms, which typically have a &quot;delete on
            last close&quot; semantics, while such operations will succeed, the bytes
            are still consuming space on disk.  For many applications this
            limitation is not a problem (e.g. if you have plenty of disk space,
            and you don't rely on overwriting files on Windows) but it's still
            an important limitation to be aware of.
            
            <p/>This class supplies the workaround mentioned in the bug report

            If we were using Java 1.5, we could use LinkedHashMap and we would not need this thread
            to clean out the cache.
            
            The SortedSet sortedFilterItems is used only to sort the items from the cache,
            so when it's time to clean up we have the TreeSet sort the FilterItems by
            timestamp.
            
            Removes 1.5 * the numbers of items to make the cache smaller.
            For example:
            If cache clean size is 10, and the cache is at 15, we would remove (15 - 10) * 1.5 = 7.5 round up to 8.
            This way we clean the cache a bit more, and avoid having the cache cleaner having to do it frequently.

            <summary> <p/>Implements {@link LockFactory} using native OS file
            locks.  Note that because this LockFactory relies on
            java.nio.* APIs for locking, any problems with those APIs
            will cause locking to fail.  Specifically, on certain NFS
            environments the java.nio.* locks will fail (the lock can
            incorrectly be double acquired) whereas {@link
            SimpleFSLockFactory} worked perfectly in those same
            environments.  For NFS based access to an index, it's
            recommended that you try {@link SimpleFSLockFactory}
            first and work around the one limitation that a lock file
            could be left when the JVM exits abnormally.<p/>
            
            <p/>The primary benefit of {@link NativeFSLockFactory} is
            that lock files will be properly removed (by the OS) if
            the JVM has an abnormal exit.<p/>
            
            <p/>Note that, unlike {@link SimpleFSLockFactory}, the existence of
            leftover lock files in the filesystem on exiting the JVM
            is fine because the OS will free the locks held against
            these files even though the files still remain.<p/>
            
            <p/>If you suspect that this or any other LockFactory is
            not working properly in your environment, you can easily
            test it by using {@link VerifyingLockFactory}, {@link

            <p/>
            The native lucene index order is used to assign an ordinal value for each field value.
            <p/>
            Field values (terms) are lexicographically ordered by unicode value, and numbered starting at 1.
            <br/>
            Example of reverse ordinal (rord):
            <br/>If there were only three field values: "apple","banana","pear"
            <br/>then rord("apple")=3, rord("banana")=2, ord("pear")=1
            <p/>
            WARNING: 
            rord() depends on the position in an index and can thus change 
            when other documents are inserted or deleted,
            or if a MultiSearcher is used.

            <p/><b>NOTE</b>: with the switch in 2.9 to segment-based

            and a type string.
            <p/>
            The start and end offsets permit applications to re-associate a token with
            its source text, e.g., to display highlighted query terms in a document
            browser, or to show matching text fragments in a <abbr title="KeyWord In Context">KWIC</abbr> display, etc.
            <p/>
            The type is a string, assigned by a lexical analyzer
            (a.k.a. tokenizer), naming the lexical or syntactic class that the token
            belongs to.  For example an end of sentence marker token might be implemented
            with type "eos".  The default token type is "word".  
            <p/>
            A Token can optionally have metadata (a.k.a. Payload) in the form of a variable
            length byte array. Use {@link TermPositions#GetPayloadLength()} and 
            {@link TermPositions#GetPayload(byte[], int)} to retrieve the payloads from the index.

            <summary><br/><br/>
            </summary>
            <summary><p/><b>NOTE:</b> As of 2.9, Token implements all {@link Attribute} interfaces
            that are part of core Lucene and can be found in the {@code tokenattributes} subpackage.
            Even though it is not necessary to use Token anymore, with the new TokenStream API it can
            be used as convenience class that implements all {@link Attribute}s, which is especially useful
            to easily switch from the old to the new TokenStream API.
            </summary>
            <summary><br/><br/>
            <p/><b>NOTE:</b> As of 2.3, Token stores the term text
            internally as a malleable char[] termBuffer instead of
            String termText.  The indexing code and core tokenizers
            have been changed to re-use a single Token instance, changing
            its buffer and other fields in-place as the Token is
            processed.  This provides substantially better indexing
            performance as it saves the GC cost of new'ing a Token and
            String for every term.  The APIs that accept String
            termText are still available but a warning about the
            associated performance cost has been added (below).  The
            {@link #TermText()} method has been deprecated.<p/>
            </summary>
            <summary><p/>Tokenizers and TokenFilters should try to re-use a Token instance when
            possible for best performance, by implementing the
            {@link TokenStream#IncrementToken()} API.
            Failing that, to create a new Token you should first use
            one of the constructors that starts with null text.  To load
            the token from a char[] use {@link #SetTermBuffer(char[], int, int)}.
            To load from a String use {@link #SetTermBuffer(String)} or {@link #SetTermBuffer(String, int, int)}.
            Alternatively you can get the Token's termBuffer by calling either {@link #TermBuffer()},
            if you know that your text is shorter than the capacity of the termBuffer
            or {@link #ResizeTermBuffer(int)}, if there is any possibility
            that you may need to grow the buffer. Fill in the characters of your term into this
            buffer, with {@link String#getChars(int, int, char[], int)} if loading from a string,
            or with {@link System#arraycopy(Object, int, Object, int, int)}, and finally call {@link #SetTermLength(int)} to
            set the length of the term text.  See <a target="_top" href="https://issues.apache.org/jira/browse/LUCENE-969">LUCENE-969</a>
            for details.<p/>
            <p/>Typical Token reuse patterns:
            <ul>
            <li> Copying text from a string (type is reset to {@link #DEFAULT_TYPE} if not
            specified):<br/>
            <pre>
            return reusableToken.reinit(string, startOffset, endOffset[, type]);
            </pre>
            </li>
            <li> Copying some text from a string (type is reset to {@link #DEFAULT_TYPE}
            if not specified):<br/>
            <pre>
            return reusableToken.reinit(string, 0, string.length(), startOffset, endOffset[, type]);
            </pre>
            </li>
            <li> Copying text from char[] buffer (type is reset to {@link #DEFAULT_TYPE}
            if not specified):<br/>
            <pre>
            return reusableToken.reinit(buffer, 0, buffer.length, startOffset, endOffset[, type]);
            </pre>
            </li>
            <li> Copying some text from a char[] buffer (type is reset to
            {@link #DEFAULT_TYPE} if not specified):<br/>
            <pre>
            return reusableToken.reinit(buffer, start, end - start, startOffset, endOffset[, type]);
            </pre>
            </li>
            <li> Copying from one one Token to another (type is reset to
            {@link #DEFAULT_TYPE} if not specified):<br/>
            <pre>
            return reusableToken.reinit(source.termBuffer(), 0, source.termLength(), source.startOffset(), source.endOffset()[, source.type()]);
            </pre>
            </li>
            </ul>
            A few things to note:
            <ul>
            <li>clear() initializes all of the fields to default values. This was changed in contrast to Lucene 2.4, but should affect no one.</li>
            <li>Because <code>TokenStreams</code> can be chained, one cannot assume that the <code>Token's</code> current type is correct.</li>
            <li>The startOffset and endOffset represent the start and offset in the
            source text, so be careful in adjusting them.</li>
            <li>When caching a reusable token, clone it. When injecting a cached token into a stream that can be reset, clone it again.</li>
            </ul>
